(NewsNation) — As the Democratic National Convention gets underway in Chicago, the Republican ticket is making a push for the key swing states, hoping to boost support among working-class voters in rural areas.

Former President Donald Trump spoke in Pennsylvania Monday, his second stop in the state in three days before he heads to Michigan.

Energy and the economy were in the spotlight during Trump’s rallies in York and Wilkes-Barre. His messaging hit on fracking, gas prices and inflation, issues voters on the ground say are very important to them in the upcoming election.

“Very simply, Kamala Harris is an economy wrecker and a country destroyer. Our country will be destroyed if she gets in, Kamala Harris can’t answer how she’d pay for any of her new radicalized liberal spending schemes that will bankrupt our country,” Trump said on Monday in York, Pennsylvania.

Trump also took the opportunity to attack his opponent, Vice President Kamala Harris, who he has taken to calling “Comrade Kamala“.

“Your state’s going to be ruined anyway. She’s (Harris) totally anti-fracking. She’s been anti-fracking and anti-drilling, anti-oil and gas, from practically the day she was born. All of a sudden, a couple of months ago, she said, I’d love to have fracking. Now, she won’t have fracking. Vote Trump, and your incomes will soar, your savings will grow, and young people will be able to afford a home,” Trump said on Saturday.

Trump delivered his remarks from a manufacturing facility, a significant change from the huge arenas and open-air rally sites he has been campaigning at.

Trump hammered Harris on the economy, associating her with rises in inflation that occurred during the Biden administration and likening her latest proposal against price gouging to measures in communist nations. Trump has said a federal ban on price gouging for groceries would lead to food shortages, rationing and hunger.

“When I’m back in the White House, America’s future will be built right here in Pennsylvania. The number one step we will take to launch a great American manufacturing renaissance will be to end Kamala Harris’ war on American energy. On day one I will tell the frackers and energy workers of Pennsylvania to drill, baby drill,” Trump said.

This is a key message in Pennsylvania, which is the second biggest producer of natural gas in the country, behind Texas. The state makes up over 100,000 jobs and has an economic impact to the tune of $41 billion. Voters on the ground tell NewsNation all they can think about is the economy, their jobs, their livelihoods, and how to make ends meet.

“The price of food is going up, medical has gone up, housing has gone up, it’s really, it’s terrible,” one Trump supporter told NewsNation, adding, “He’s (Trump) a man of his word, and he’s for the people. He’s for the country, and we need him in.”

Pennsylvania has 19 electoral votes up for grabs in November, making it a critical battleground for both candidates, who are neck and neck in the state. The latest Decision Desk HQ polls show Harris just 1.5 percentage points above Trump.
